GGZ Gaming Zone: main server The GGZ server (ggzd) is the central part of the server-side infrastructure of the GGZ Gaming Zone. It provides player account management, game server launches, and administration of the statistics database, as well as secure chat rooms. You do not require this package if you simply want to play online games. You will need it, however, if you intend to do any game hosting, either because you want to run your own server or for development purposes. This package is part of the GGZ Gaming Zone, a multiuser networked gaming environment.
